When we met Corey Bohl and his 1967 Nova, he was in first place in the Gasser B class of the 2022 Midwest Drags. We caught Corey and his dad Carl at the Morocco-based Motorplex US41. The two-man team ripped the Nova off and had the car’s hood exposing its small 427 cubic inch Chevy engine block. Naturally, we wanted to know more and couldn’t look away from the transparent valve covers either.

It turned out that Corey had Ohio Crankshaft build the small-block Chevy engine. They assembled the entire long block and selected the components for construction.

“The small block features 4,000″ stroke and 6,000 rods,” Bohl told us. “It just has a flat-top piston with 11:1 compression. Everything down to the tappets is from Ohio Crankshaft Straub Technologies out of Tennessee designed me a hydraulic roller camshaft The engine has Morel tappets BES Racing Engines and Tony Bischoff ported the CNC cylinder heads I also threw a Victor Tunnel Ram on it to give it that cool factor, and it’s backed by a GForce 4-speed and Ram clutch.Up top, the engine also has COMP Cams Pro Magnum roller rocker arms and two 650 Holley carburetors made by ATM Innovation in Bowling Green, KY. also a studded belt, Doug’s 2-inch primary manifolds and clear valve covers, which are everyone’s favorite.

Corey’s Nova looked extremely impressive, but he told us that construction started as a $3,000 Craigslist find over a decade ago.

“I paid $3,000 for the car when I was about 19,” Bohl says. “I happened to have three thousand dollars because I sold a vehicle the day before. The car was on Craigslist back when it was a thing. I took the car home and it was a six-cylinder Powerglide. It was red with a black interior. He was in really good condition.

“Well, fast forward through the kids and meet my wife Sarah, and we put the car on a rotisserie and I took it all apart. We had it painted and then everything else pretty much happened at home with me and my dad. I knew I wanted a gas from day one. Wasn’t expecting it to be a 10 second tram, but it was a hell of a ride.

Competing in the Gasser B class for the Midwest Drags, Corey had run a 10.69 and a 10.68 at this point in the competition.

“I was happy with that,” he says. “The small block gives us about 675 horsepower. With less humidity and starting at a little higher rpm, I would like to get back into the 10.50. It was already 10:40 a.m.
